Description

Technical Field

[0001] This utility model relates to the technical field of arch-breaking devices, and in particular to an arch-breaking device for wet sludge silos. Background Technology

[0002] Wet sludge is a byproduct of wastewater treatment, characterized by high water content and high viscosity. During storage and transportation, it is highly susceptible to adhesion, arching, and even blockage near the silo outlet. Under the influence of its own weight and the friction of the silo walls, the wet sludge inside the silo often forms a stable arched structure, hindering its smooth discharge and severely impacting the continuity and stability of subsequent treatment processes. Therefore, preventing outlet blockage is a critical issue that urgently needs to be addressed to ensure the normal operation of the sludge treatment system.

[0003] Currently, to address the arching problem of wet sludge, the industry typically installs various types of mechanical arch-breaking devices at the silo outlet. These devices mostly attempt to break the formed arch structure through simple rotation or reciprocating motion. However, such unidirectional arch-breaking methods often have limited range of action and insufficient breaking force, making it difficult to completely and effectively eliminate the solidified arches formed by highly viscous and easily compressible wet sludge. Some devices also suffer from complex structures, high energy consumption, and limited arch-breaking effects, failing to achieve stable and efficient arch-breaking operations under the unique physical characteristics of wet sludge, thus affecting the efficiency and reliability of the entire sludge treatment system. Utility Model Content

[0004] This utility model relates to a wet sludge silo arch-breaking device with a reasonable structure and higher arch-breaking efficiency.

[0005] The technical solution adopted by this utility model is as follows: a wet sludge silo arch-breaking device is installed at the silo outlet. A support plate is fixedly connected to the outside of the silo outlet, and a motor is fixedly installed on the support plate. A first bevel gear is fixedly connected to the output end of the motor. An inner rotating shaft is passed through the side wall of the silo outlet. A first rotating sleeve and a second rotating sleeve are rotatably connected to the inner rotating shaft. The first rotating sleeve and the second rotating sleeve pass through the two side walls of the silo outlet and are rotatably connected to them. An arch-breaking rotating blade is fixedly fitted on the inner rotating shaft and is located inside the silo outlet. A second bevel gear that meshes with the first bevel gear is fixedly connected to one end of the inner rotating shaft. A third bevel gear that meshes with the first bevel gear is fixedly fitted to one end of the first rotating sleeve. The outer sides of the first rotating sleeve and the second rotating sleeve are connected by multiple linkage rods. Multiple arch-breaking rods are fixedly connected to the linkage rods.

[0006] As a further improvement of this utility model, the inner rotating shaft is rotatably connected to the first rotating sleeve through two bearings. The bearing is set on the outside of the inner rotating shaft and located inside the first rotating sleeve. The inner ring of the bearing is fixedly connected to the inner rotating shaft, and the outer ring of the bearing is fixedly connected to the first rotating sleeve.

[0007] As a further improvement of this utility model, the inner rotating shaft is rotatably connected to the second rotating sleeve through two bearings. The bearings are sleeved on the outside of the inner rotating shaft and located inside the second rotating sleeve. The inner ring of the bearings is fixedly connected to the inner rotating shaft, and the outer ring of the bearings is fixedly connected to the second rotating sleeve.

[0008] As a further improvement of this utility model, the first rotating sleeve is rotatably connected to the side wall of the material outlet of the hopper through a bearing three. The bearing three is sleeved on the outside of the first rotating sleeve, the inner ring of the bearing three is fixedly connected to the first rotating sleeve, and the outer ring of the bearing three is fixedly connected to the side wall of the material outlet of the hopper.

[0009] As a further improvement of this utility model, the second rotating sleeve is rotatably connected to the side wall of the material outlet of the hopper through a bearing four. The bearing four is sleeved on the outside of the second rotating sleeve, the inner ring of the bearing four is fixedly connected to the second rotating sleeve, and the outer ring of the bearing four is fixedly connected to the side wall of the material outlet of the hopper.

[0010] As a further improvement of this utility model, both the first rotating sleeve and the second rotating sleeve extend into the inside of the hopper outlet, and the arch-breaking rotating blade is located between the first rotating sleeve and the second rotating sleeve.

[0011] As a further improvement of this utility model, the second bevel gear and the third bevel gear are arranged opposite to each other and cooperate with the first bevel gear to form a coaxial and reverse meshing structure.

[0012] The beneficial effects of this utility model are as follows: By driving the first bevel gear with a single motor to synchronously mesh with the second and third bevel gears, a compact coaxial reverse transmission structure is formed. This causes the arch-breaking rotating blades on the inner rotating shaft and the arch-breaking rod assembly composed of the first rotating sleeve, the second rotating sleeve, and the linkage rod to rotate at high speed in opposite directions. This creates a strong shearing and stirring effect inside the silo outlet, thereby efficiently breaking up the solid arches formed by wet sludge. This completely solves the problems of limited range and insufficient arch-breaking force of traditional unidirectional arch-breaking devices. The device has a reasonable and compact structural design, stable and reliable transmission, and significantly improves the arch-breaking efficiency and thoroughness. It effectively ensures the continuity and stability of the wet sludge silo discharge, while also having the advantages of low energy consumption and easy maintenance. Attached Figure Description

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides the following: Figure 1-4The device shown is a wet sludge silo arch-breaking device, which is installed at the silo outlet 1. A support plate 2 is fixedly connected to the outside of the silo outlet 1. A motor 3 is fixedly installed on the support plate 2. A first bevel gear 4 is fixedly connected to the output end of the motor 3. An inner rotating shaft 5 is installed through the side wall of the silo outlet 1. A first rotating sleeve 6 and a second rotating sleeve 7 are rotatably connected to the inner rotating shaft 5. The first rotating sleeve 6 and the second rotating sleeve 7 pass through the two side walls of the silo outlet 1 and are rotatably connected to them. An arch-breaking rotating blade 8 is fixedly installed on the inner rotating shaft 5 and is located inside the silo outlet 1. A second bevel gear 9 that meshes with the first bevel gear 4 is fixedly connected to one end of the inner rotating shaft 5. A third bevel gear 10 that meshes with the first bevel gear 4 is fixedly installed on one end of the first rotating sleeve 6. The outer sides of the first rotating sleeve 6 and the second rotating sleeve 7 are connected by multiple linkage rods 11. Multiple arch-breaking rods 12 are fixedly connected to the linkage rods 11.

[0022] like Figure 2 As shown, in this utility model, the inner rotating shaft 5 is rotatably connected to the first rotating sleeve 6 through two bearings 13. The bearings 13 are sleeved on the outside of the inner rotating shaft 5 and located inside the first rotating sleeve 6. The inner ring of the bearings 13 is fixedly connected to the inner rotating shaft 5, and the outer ring of the bearings 13 is fixedly connected to the first rotating sleeve 6. By setting the bearings 13, the relative rotational accuracy between the inner rotating shaft 5 and the first rotating sleeve 6 can be effectively guaranteed, while reducing the coefficient of friction during the rotation process and improving the transmission efficiency.

[0023] like Figure 2 As shown, in this utility model, the inner rotating shaft 5 is rotatably connected to the second rotating sleeve 7 through two bearings 14. The bearings 14 are sleeved on the outside of the inner rotating shaft 5 and located inside the second rotating sleeve 7. The inner ring of the bearings 14 is fixedly connected to the inner rotating shaft 5, and the outer ring of the bearings 14 is fixedly connected to the second rotating sleeve 7. By setting the bearings 14, the relative rotational accuracy between the inner rotating shaft 5 and the second rotating sleeve 7 can be effectively guaranteed, while reducing the coefficient of friction during the rotation process and improving the transmission efficiency.

[0024] like Figure 4 As shown, in this utility model, the first rotating sleeve 6 is rotatably connected to the side wall of the hopper outlet 1 via a bearing 3 15. The bearing 3 15 is sleeved on the outside of the first rotating sleeve 6, the inner ring of the bearing 3 15 is fixedly connected to the first rotating sleeve 6, and the outer ring of the bearing 3 15 is fixedly connected to the side wall of the hopper outlet 1. The setting of the bearing 3 15 realizes the rotational support between the first rotating sleeve 6 and the hopper outlet 1. The fixed connection between its outer ring and the side wall of the hopper outlet 1 ensures the axial positioning of the first rotating sleeve 6 during rotation and prevents it from axially moving.

[0025] like Figure 4As shown, in this utility model, the second rotating sleeve 7 is rotatably connected to the side wall of the material outlet 1 of the hopper through a bearing 16. The bearing 16 is sleeved on the outside of the second rotating sleeve 7, the inner ring of the bearing 16 is fixedly connected to the second rotating sleeve 7, and the outer ring of the bearing 16 is fixedly connected to the side wall of the material outlet 1 of the hopper. The bearing 16 provides rotational support between the second rotating sleeve 7 and the material outlet 1 of the hopper. The fixed connection between its outer ring and the side wall of the material outlet 1 of the hopper ensures the axial positioning of the second rotating sleeve 7 during rotation and prevents it from axially shifting.

[0026] like Figure 2-4 As shown, in this utility model, both the first rotating sleeve 6 and the second rotating sleeve 7 extend into the inside of the hopper outlet 1, and the arch-breaking rotating blade 8 is located between the first rotating sleeve 6 and the second rotating sleeve 7. The arch-breaking rotating blade 8 is arranged between the two rotating sleeves, which can make full use of the rotational kinetic energy of the middle part of the inner rotating shaft 5, so that it can directly act on the wet sludge in the central area of ​​the hopper outlet 1 when rotating, forming an arch-breaking area with the outer arch-breaking rod 12, and at the same time ensuring that the arch-breaking rod 12 on the linkage rod 11 can cover most of the space from the inner wall of the hopper outlet 1 to the central area.

[0027] like Figure 1-4 As shown, in this utility model, the second bevel gear 9 and the third bevel gear 10 are arranged opposite to each other and cooperate with the first bevel gear 4 to form a coaxial and opposite meshing structure.

[0028] When the motor 3 drives the first bevel gear 4 to rotate clockwise, the second bevel gear 9, which meshes with the lower side of the first bevel gear 4, will drive the inner rotating shaft 5 to rotate counterclockwise, thereby causing the arch-breaking rotating blade 8 to rotate counterclockwise; at the same time, the third bevel gear 10, which meshes with the upper side of the first bevel gear 4, will drive the first rotating sleeve 6 to rotate clockwise. Through the transmission of the linkage rod 11, the second rotating sleeve 7 rotates clockwise synchronously with the first rotating sleeve 6, so that the entire arch-breaking rod 12 rotates clockwise around the axis of the inner rotating shaft 5.

[0029] Working principle: In the specific implementation of this utility model, when wet sludge accumulates towards the discharge port 1 of the silo under the action of gravity, it easily forms a stable arched blockage structure in the discharge port area. At this time, the motor 3 is started, and the output end of the motor 3 drives the first bevel gear 4 to rotate at a set speed. Through the meshing transmission of the bevel gear, the inner rotating shaft 5 and the first rotating sleeve 6 move in opposite directions.

[0030] Specifically, the inner rotating shaft 5 drives the arch-breaking rotating blades 8 to perform high-speed rotating shearing in the central area of ​​the silo outlet 1. The blade edges generate strong relative motion with the wet sludge, directly tearing the dense arch structure in the central area and simultaneously pushing the crushed sludge outwards. Meanwhile, the annular frame formed by the first rotating sleeve 6 and the second rotating sleeve 7 connected by the linkage rod 11 drives the arch-breaking rod 12 to rotate in the opposite direction around the axis of the inner rotating shaft 5. During rotation, the arch-breaking rod 12 can multi-dimensionally disturb the wet sludge near the inner wall and in the central area of ​​the silo outlet 1. On one hand, the radial extension structure of the arch-breaking rod 12 can insert into the weak points of the arch, directly destroying the structural stability of the arch through mechanical force. On the other hand, the uniform distribution of multiple arch-breaking rods 12 in the circumferential direction can form a continuous mixing zone, scraping away and breaking up the adhering sludge near the silo wall, preventing secondary arching.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
